I have created a Feedback. FB18243622

It is definitely specific to Logic Pro, yes. But Feedback is for bug reports and feature requests, right? This is not what I'm trying to do. I would like to understand the correct way to send MIDI to Logic Pro. I want to figure out how to structure my ItemProvider so Logic Pro accepts it. Is this documented somewhere?

That's nice! Except it's "macOS 15.0", not 18.0 ;)
